Fragmentary Partbooks c. 1520
The following sequence of images demonstrates how the fragments were reconstructed using Photoshop.
F. 50r was upside down when it was glued to f. 49v. Therefore, to put the stray notes in their proper orientation with respect to f. 49v, we must flip and rotate f. 50r. When the image layer containing these extra notes overlays the image of f. 49v, we see an enhanced version of f. 49v.
Further enhancement of f. 49v occurs when the image of a completely separate fragment is reattached.
The images above are 72 dpi. A 150 dpi image of f.50r gives scholars a chance to examine the manuscript more closely.
F. 49v and f. 50r contain motet no. 44. A transcription in modern notation is available.
